1, 04 and 3 16 stainless steels are all food grade stainless steels, but the corrosion resistance and high temperature resistance of 3 16 stainless steel are better than that of 304 stainless steel.
2. The application scope of the market is different: 304 stainless steel is relatively low in price and is usually used in daily life, such as kettles and chopsticks. 3 16 stainless steel is on the high side.
3. Their metal compositions are different: the China element corresponding to 304 stainless steel is 0Cr18Ni9; ; The China element of 3 16 stainless steel is 0Cr 17Ni 12Mo2. The average nickel content of 304 stainless steel is 9%, and that of 3 16 stainless steel is 0/2%.
4. Different properties: 304 stainless steel can't be strengthened by heat treatment, can't be quenched like carbon steel, and has no magnetism. 3 16 stainless steel has better acid and alkali resistance and high temperature resistance than 304.
